Hi,After some months, I'm able to pick this up again after I ran out of time last attempt due to display issues (partially overcome)

The cd loads stuff & I can get past the display selection screen by cancelling it. At this stage, the keyboard (tried PS2 & USB, both working fine on other PCs) will work & can move the cursor.

The process then moves on to the pale blue install screens, during which I select the keyboard type & most times the keyboard then doesn't work. By the time I get to the "enter password" section, I have not got keyboard input and there are no LEDs lit on the keyboard. If I open a terminal, I can't type there either, but a keypress causes the cursor to blink, so some kind of signal is being received. I have done this a number of times with the same results.

Mouse works fine.

I've trawled the web but haven't found any problem that seems similar. There was one, for which a possible solution was "Try booting into TUI once before rebooting into the GUI login." - how do I do that?
